About this 0.51ct lab-grown princess diamond

This 0.51ct lab-grown princess sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836610907 or 836610907. Listed at 18 retailers as of October 30, 2026, with prices from £203 to £995, a £792 spread on the same certified stone. Reve Diamonds lists it at £995. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
